Duping still possible?

If you remember the old GuildHall dupe, you had account A going into GuildHall trading items over to account B. When account A come into the GuildHall it had the duped items. This dupe can work in any portal with enough lag, Kabams efforts to stop this ended up with *account in use* and 51 gold pirate keys in nexus. I duped with the pirate keys in uswest but now that it's 51 gold I can't open them in nexus but it must be still possible. If we had enough lag in the realms we could use the ahk script from the old dupe and use it in any dungeon portal. I tested this in the Euwest2 fame train, no success yet.

What if we all went to the same server/realm and went through the same portal, would that cause enough lag to dupe?

it's fixed,
and if not.. good luck waiting 10 minutes every dupe
